In the 50 Figure 2 1S a VleW ln 51de@16173171011 0f the d1@ embodiments shown such connection is in theshown in Figure 1 part being in section to reveal foym Gf telespingmembers y and 3, Membgr the relation of the parts, and showing a shoe 'imay be provided with an internal spring (not upper in position foroperation. shown) arranged to bias member il upwardly Figure 3 is adetail View taken from the rear relative to member l. While Figures 1and 2 55 show the hinge connection only at the right hand rear corner ofplate 6, it will be understood that an identical hinge connection isprovided at the left hand rear corner thereof, as. shown in Figure 3.

In order to accomplish quick detachment and inter-change of plate 6, inaccordance with the present invention, the member 8 may be arranged toreadily release a cooperating hinge part carried by plate 6. In theembodiment shown in the drawing member 8 is of furcated structure withlegs 9 and I0, the former leg being substantially shorter than thelatter as shown clearly in Figure 3. Depending from plate 6 is a tenonmember II arranged to t into the space between legs 9 and I@ of furcatedmember 8. The longer leg Ill of furcated member 3 is provided with ahinge pin I2 extending laterally therefrom and arranged to cooperatewith an aperture i3 in tenon member I l. The position of hinge pin l2 issuch that, in ordinary operation upon opening and closing plate E to anextent sufcient for the insertion and release of work parts, tenonmember I I is retained between legs S and IQ of furcated member 8; whenplate 5 is swung to an extreme position, however, as for instance, theposition illustrated in dotted lines in Figure 2 tenon member II is thenentirely above the shorter leg 9 and hence plate ii may be released fromthe hinge connection by sidewise translation thereof (to the right asseen in Figure 1) relative to base I until hinge pin I2 is withdrawnfrom aperture i3.

It will be observed that the hinge connection at the right-hand rearcorner of plate 5, shown in Figure l, is` identical with the hingeconnection at the left-hand rear corner, shown in Figure 3, sol that theshorter leg S is, in each instance, on the right-hand side (as viewed inFigure l) of the longer leg I6. However, it will be understood that theshorter legs might'be arranged on the opposite side of the longer legs,the side being immaterial provided both shorter legs are on the sameside of their respective longer legs.

In the embodiment shown in the drawing, plate 6 is provided with acut-out area Ili adjacent the cutting edges of die li, and is furtherprovided with a gaging tip I5 whereby the Work, such as a shoe upper,may be properly aligned with reference to the die, as for instance, bycoordinating gaging tip I5 with a line of stitching or other marks uponthe shoe upper.

In the embodiment shown in the accompanying drawing plate 6 extendsforwardly beyond die l and overlies a work support VI@ as clearly shownin Figure 2. Such a Work support i5 be in the form of a bight rod theends of which are fitted into sockets in the base I, as shown at i6, andsuitably secured therein, as for instance, by means of set Screw I2.Such a bight rod is shown in detail in Figure 4 and is provided with acentral bight portion I9 the upper edge of which is at substantially theelevation of and aligned with the cutting edges 5 of die 4.

l/Vith the parts arranged in this manner the Work, such as a iitted shoeupper 2&3, may be draped over die d and work support i6, and adjusteduntil properly aligned with reference to gaging tip I5. Such anadjustment of the position or" upper 2l! may be readily accomplished bythe operator who is gripping the upper Z between work support I S andthe forward end of plate 6. The open center of portion iS of Worksupport I6 facilitates such adjustment and clamping since by grippingthe assembly, as shown in Figure 2, the tip of one iinger is engagedwith the lower surface upper 20 so that it may be moved to a limitedextent without changing the position of the hand except to release thepinching grip upon plate 6 and work support I6. When the upper isproperly positioned, the operator grips the upper between work supportI6 and plate 6, and actuates a press to accomplish the cut-out orperforation.

From the foregoing description it will be apparent that the presentinvention accomplishes its object and provides a die wherein both thecutting element and the gaging device may be readily removed andinter-changed, and at the same time provides a die of such characterthat a iitted shoe upper may be draped over and effectively clamped to awork support while at all times the operator is enabled to make minoradjustment in the relation of the work to the die.

It is apparent that many modifications in the details and arrangementsof part of the die herein disclosed Will present themselves to thoseskilled in the art without departing from the spirit of this invention.It is to be distinctly understood, therefore, that the embodiment shownin the accompanying drawing and hereinbefore described in detail ismerely for the purpose of illustration and that 'the invention is notlimited to such illustrative embodiment.
